SPINNING RING Filed May 14, 1963 INVENTOR. L 00/5 H /70R //v ATTORNEYUnited States Patent 3,205,646 SPINNING RING Louis H. Morin, Bronx,N.Y., assignor to Coats & Clark Inc., New York, N .Y., a corporation ofDelaware Filed May 14, 1963, Ser. No. 280,346 1 Claim. (Cl. 57119) Thisinvention relates to traveler rings, wherein the body portion of thering is formed as a die casting in providing a rigid, as well aslightweight body. More particularly, the invention deals with a ring ofthe character defined, wherein the traveler engaging portions of thering are covered with a plastic coating, preferably by injection moldingof the plastic on said portion of the ring.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

FIG. 1 is a plan view of a ring made according to my invention; and

FIG. 2 is an enlarged broken section on the line 2-2 of FIG. 1.

Considering FIG. 2 of the drawing, it will appear that the metallic ringbody comprises an inner annular traveler engaging portion 11, the outersurface of which has an annular enlargement 12 centrally thereofterminating at one side in an extending flange portion 13. The portion11 has annular diverging rims 14 and 15 extending beyond the surfaces of12, the rim 14 being preferably of less thickness than the rim 15, asclearly noted in FIG. 2 of the drawing. It will also appear that theouter surface of the rim 14 is beveled, as seen at 14. The body 10 isformed as a die cast product, preferably of aluminum or magnesium to belight in weight.

Applied to the portion 11, including the rims 14 and 15, is a shellcoating 16 of suitable plastic material. In applying this coating inaccordance with one method of producing the end product, the coating 16is injection molded onto the portion 11, including the rims 14 and 15,by the use of such plastic materials as nylon, Delrin, Celcon orfluorocarbons, such as Teflon and Kel-F, to provide on the portion 11and rims 14 and 15 a smooth wearing surface, upon which the travelersoperate.

3,205,645 Patented Sept. 14, 1965 Production of traveler rings inaccordance with the structure above defined will not only result inproducing a lightweight, economical and, yet, strong and durablestructure, but will also obviate the necessity of lubrication of a ringor the need for cleaning, bufiing or otherwise processing metal rings,as commonly employed.

By virtue of the cross-sectional contour of the ring, as clearly notedin FIG. 2 of the drawing, it will be apparent that the metallic rigidbody portion of the ring can be readily die cast and, further, the shellplastic coating 16 can be easily applied by reason of the coating havingwhat may be defined as ring portions 16' and 16", which are hook-shapedin cross-sectional form and which envelop the rims 14 and 15, leaving 12and the flange 13 uncovered or uncoated.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

A traveler ring of the character defined, said ring comprising ametallic ring body having a flanged large diameter central portion andan inner annular traveler engaging portion terminating in side rims,said side rims extending from said flanged large diameter centralportion, one of said rims being thicker adjacent the said large diametercentral portion than at its edge remote from said central portion and aninjection molded shelllike coating of plastic material completelyenveloping the traveler engaging portion and the rims thereof.
